Strict types (scalar type hints for method signatures) have been around since PHP 7, and since then I would say it is recommended to always use === (with type check) over == (no type check) so one would have enough time to upgrade it‘s code. And it also just makes sense from the language design perspective to fix that behaviour. Having a major version coming is a good time to fix such stuff imho.
